Re: Not saving windows

Ah, in version 1.23 it's on page 18 onwards. I was looking at v1.22. I think the method is the same though. You might also find help on the SDRUno page on Facebook. It's a busy site with lots of helpful people.

Re: Not saving windows

Hello. The method outlined on pages 12 &13 of the manual is correct as far as I recall.

Re: RSP2 no BBC Radio 4 on LW?

Wide, buzzing carriers from switch-mode PSUs are a pain in the neck on LF. The best you can do is to use a loop antenna sited as far as possible from any suspected source of noise. Not easy these days! For feeding the Hi z connector with coax, link N to G and connect outer to G and inner to P. For a...

Re: RSP2 no BBC Radio 4 on LW?

Yes, the MW/FM rejector disappears in H-z mode. A homebrew LPF (or a commercial one) is a good idea, as is careful control of the RF gain/attenuation slider.

Re: RSP2 no BBC Radio 4 on LW?

Oh yes, the RSP2 does indeed receive well down to VLF. It's my 'go to' LF receiver, as it works well right down to 15 kHz at least. It's all there, BBC R4, MSF (60 KHz) and all the other stuff including SAQ on 17.2 kHz on those special occasions. The Hi-Z port is best for LF, but you should get resu...

Re: SOUND BUFFERING ABOVE SAMPLE RATE 5

I use my RSP2 with SDRUno and it runs without problem. Below 6 MHz sample rate I can surf the web, play music etc at the same time, but above this I have to reduce the processor load a bit. SDRUno running on its own will reach 10 MHz b/w without any glitching. This is v1.22 and my laptop is a mid-sp...

Re: My winndow only goes down to 120 dbm

Hello. The displayed noise level will depend on the sample rate/bandwidth you have selected. Try selecting a narrow bw (maybe 2MHz sample rate with 8 decimation) and then a wider one (try 2 MHz with 1 decimation) and you will see the difference.

Re: RA0SMS vs PA0RDT Active Mini Whip - RA0SMS is Very Noisy - Why?

Peaks every 10 kHz sounds familiar - where are you located? If you are in the USA, then this may be intermodulation from MW broadcast stations which are spaced by 10 kHz. It sounds like the RA0SMS antenna may be a sub-standard design compared to the PA0RDT. Yes, I am in the US. I tried a broadcast ...

Re: What’s going on here ?? Receiving but no antenna

I've lost track - is it picking stuff up with nothing connected to the antenna socket, or with the balun connected?
